Definitions

  • polyvalent metal oxides adsorb the oleophilic component of the oleophilic area forming particles during the course of the plate making since they have high adsorbability, whereby the effects of enhancing the plate wear of the oleophilic area can be obtained.
  • the contact area of the hydrophilic polymer and the polyvalent metal oxide becomes small, whereby the effects as described above cannot sometimes be obtained satisfactorily.
  • the present invention provides a liquid heat sensitive material for use in making lithography characterized in that it includes: fine particles changed when heated and thereby forming an oleophilic area on the plate surface; a hydrophilic polymer having Lewis base moieties containing nitrogen, oxygen or sulfur; a polyvalent metal oxide; and a stabilizer for making the polyvalent metal oxide inert to the above hydrophilic polymer.
  • the liquid at room temperature not only the liquid at room temperature but also the heated or cooled liquid can be used.
  • the liquid temperature at the time of removing the stabilizer must be determined according to the bloating tendency and mechanical strength of the coat and the temperature characteristics of the oleophilic area forming particles so as to be within the range of not destroying the satisfactory characteristics thereof.
  • the previously formed coat contain the polyvalent metal oxide or the precursor thereof in the dispersed state
  • an aqueous solution or dispersion containing the polyvalent metal oxide or the precursor thereof is made to penetrate into the coat (heat sensitive layer) from its surface.
  • the solvent of the aqueous solution or the dispersion medium of the dispersion is evaporated from the coat.
  • any one of the above described processes may be adopted.
  • the molecular weight of the hydrophilic polymer added to the heat sensitive material is preferably 1,000 or more and 2,000,000 or less, more preferably 5,000 or more and 1, 000, 000 or less in terms of number average molecular weight. If the molecular weight is too low, the mechanical strength of the heat sensitive layer of the plate material cannot be ensured. If the molecular weight is too high, the viscosity of the heat sensitive material becomes high and thereby it becomes difficult to form a coat on a support by coating the same with the heat sensitive material.
  • the process for allowing the recording layer (heat sensitive layer) to contain a protective agent is, for example, as follows.
  • liquid heat sensitive material which contained microcapsules containing an oleophilic component (oleophilic area forming particles), a hydrophilic polymer having Lewis base moieties and water.
  • Propylene glycol alginate ester was added so as to improve the dispersion properties of the microcapsules in the heat sensitive material and make it easier to apply the heat sensitive material on the support.
  • a coat was formed on the surface of the same support as that of the plate material No. 1 by coating the same with the same heat sensitive material as No. 3 using a bar coater (rod number 20) and then it was air-dried at room temperature overnight to evaporate the water contained therein.
  • the support with the coat formed thereon was immersed in the above treatment liquid for 3 minutes and stood up vertically to be dried at 110°C for 5 minutes.
  • a plate material including: a support; and a heat sensitive layer containing the hydrophilic polymer (BP-A) having Lewis base moieties, the oleophilic area forming particles (microcapsules MC-A), the substance A, and polyacrylic acid as a protective agent was obtained as a plate material No. 8 for use in lithography.
  • the thickness of the obtained heat sensitive layer was 2.0 ⁇ m.
